Spyder International Junior 1/2 Zip 2026

The Piece

The Spyder kids International 1/2 Zip is exactly the kind of fleece you grab first every morning of a ski trip. It's a polyester jersey knit — not fuzzy, not heavy — so it stays slim under a shell and doesn't bunch up at the collar. The fun graphics (Cobalt Fries and Cobalt T-Rex for 2026) mean most little ones are excited to put it on without a fight, which parents tend to appreciate.

The half-zip t-neck keeps cold air off their throat when the zipper's up. Pull it down a notch when they're warming up in the lodge. That's the whole point — a layer that adjusts in five seconds. It goes on the mountain, to the rink, into the car on a cold morning. UPF 50+ in the fabric is a quiet bonus for spring ski days when the sun's strong. No PFAS chemicals in the construction, either.

This one works best as a base or mid-layer under a kids' shell on colder days. As a standalone it's good down to about 40°F, maybe a little less if they're moving. It's fitted, so size up if your kid runs between sizes or you want room for a base layer underneath. CB length at size 5 is 17 inches — it stays tucked.

Sizes run 2 through 7, which covers toddlers up through early elementary. If you're unsure where your kid lands, stop by any of our three locations and we'll help you sort it out.

Why Willi's

We've been fitting kids for the mountain since 1970 — that's a lot of winters, a lot of growing kids, and a lot of "what do I actually need?" conversations. Our staff knows this stuff cold. Come in, bring the kid, and we'll get it right.
